What could be the problem when red ligth is flashing on the hot water tank control?
If its 1 blink every 3 seconds its normal operation.
Otherwise, this is the meaning of the various blinks:
No blinks = no poilet light (not enough power (in millivolts) to keep it lit.
2 flashes = insufficient voltage (in millivolts) to gas valve.
4 flashes = high water temperature (over heat sensor activated.
5 flashes = water temperature sensor failure.
7 flashes = gas control valve / thermostat failure.
8 flashes = Only occurs if the gas control valve or Temperature knob has been turned off And the thermocouple continued to produce electric power.
9 flashes = Combustion chamber temperature sensor open or shorted.
10 flashes = LDO occurrence was detected in the combustion chamber (contaminants).

How do you light pilot on Richmond water heater
Remove the pilot cover on the outside of the water heater. Turn the gas valve knob to "Light". Using a long fireplace match or long stem lighter light the pilot. Turn the knob to "run" or "on". Replace the cover. If it will not light or stay lit, you may need a new thermocouple. They are not that expensive, but replacing them yourself can be a pain.
